Besides the fact that it stinks horribly for weeks, it has
started shedding fine particles. The thick stuff I used
before worked great. It showed signs of wear, but did not
shed any rubber. Next time I will try getting that other
formula in a thinner version.

Looking back at my posts... Apparently the only description
of the thicker version that did not shed was "recycled car
tire rubber 1/4" mat". Made by the same company (as I
recall).

I would prefer a thinner 1/8 inch version because it can be
stapled to the board. But if necessary I would again use the
1/4 inch with hot melt glue (but less glue than my first
attempt). Or maybe come up with some other easy method to
attach the rubber.

The failure has nothing to do with the thickness of the
rubber, it is apparently the type of rubber.

I use the rubber cover only for their climbing boards to
their skyway. The horizontal boards are bare wood with no
problem.
